A plane joint (arthrodial joint, gliding joint, plane articulation) is a synovial joint which, under physiological conditions, allows only gliding movement. Plane joints permit sliding movements in the plane of articular surfaces. The opposed surfaces of the bones are flat or almost flat, with movement limited by their tight joint capsules.
The cricoarytenoid joint allows for rotation and gliding motion. [1] The extent of rotation is significant, while the extent of gliding is limited. [1] The cricoarytenoid joint controls the abduction and adduction of the vocal cords. [1] It is moved by many of the intrinsic muscles of the larynx. [2]
The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. [1] According to the sliding filament theory, the myosin ( thick filaments ) of muscle fibers slide past the actin ( thin filaments ) during muscle contraction, while the two groups of filaments ...
[6]: 123 Inversion occurs at the subtalar joint and transverse tarsal joint. [7] Eversion of the foot occurs at the subtalar joint. The muscles involved in this include fibularis longus and fibularis brevis, which are innervated by the superficial fibular nerve. Some sources also state that the fibularis tertius everts. [6]: 108
The acromioclavicular joint provides the ability to raise the arm above the head. This joint functions as a pivot point (although technically it is a gliding synovial joint), acting like a strut to help with movement of the scapula resulting in a greater degree of arm rotation.
The joint allows inversion and eversion of the foot, but plays minimal role in dorsiflexion or plantarflexion of the foot. [5] The centre of rotation of the subtalar joint is thought to be in the region of the middle facet. [3] It is considered a plane synovial joint, also commonly referred to as a gliding joint. [6]
Joint mobilization is a manual therapy intervention, a type of straight-lined, passive movement of a skeletal joint that addresses arthrokinematic joint motion (joint gliding) rather than osteokinematic joint motion. It is usually aimed at a 'target' synovial joint with the aim of achieving a therapeutic effect. These techniques are used by a ...
The push-up requires the work of many muscle groups, with one of the primary muscle groups being the chest muscles, the pectoralis major and the minor. [7] These are the two large chest muscles and the main pushing muscle group of the upper body. When pushing and lowering the body during a push-up, the pectoralis major is doing most of the work.
